I have the following code:
var names = ["John Chuck", "Micheal Novak", "john Owen", "Rick John"];
names = _.sortBy( names, function( name ){
return name;
}
It gives me a sorted list of names. Now along with this if I want to do a filering, is it possible?
Its like, filter on 'John', so that final list has only 3 names with 'John' in it.
Try the following with Array.prototype.filter() and Array.prototype.includes():
var names = ["John Chuck", "Micheal Novak", "john Owen", "Rick John"];
names = _.sortBy( names, function( name ){
return name;
}).filter(n => n.toLowerCase().includes('john'));
console.log(names)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.core.min.js"></script>You can use .includes in javascript
HTML
var words = ["John Chuck", "Micheal Novak", "John Owen", "Rick John"];
const result = words.filter(word => word.includes("John"));
console.log(result); //result is: Array ["John Chuck", "John Owen", "Rick John"]
Note: .includes is Case sensitive
No, and in your particular case, you wouldn't give the 2nd argument, because you're sorting strings (unless you want to sort by a portion of the whole string...).
You would need to filter, then sort.
Since you are using Lodash.js you can also look at the _.reject function
names = _.reject(names, function(name) {
return name.match(/[.]*john[.]*/i) == undefined;
});
This will return only the 3 names. Have a look at - JSFIDDLE DEMO
A simple ES6 alternative (without any libs like Lodash):
var names = ["John Chuck", "Micheal Novak", "john Owen", "Rick John"];
var result = names.sort((a, b) => a.localeCompare(b)).filter(name => /john/gi.test(name));
console.log(result);
